Tactile Paving

[colin.telfer]

Good day

I am trying to create a tactile paving hatch based on the attached drawing where the slbs are 400mm square and it has the blister as shown. The manuals and AUtocad help don't seem to be of much help in trying to do this, can anybody help explaining what to do.
Thanks in advance

Perhaps some of the patterns posted in this thread will help.

Getting the "width" of those blisters is probably going to mean you'll need to make several circles slightly larger than each other.

Alternatively, have you tried the Express Tool SuperHatch?
